How to scroll automatically to menu when content swiped

I need to scroll menus automatically when I am swiping the content left or right, for an eg.
when I am swiping to Right and coming to 5th panel slide the navigation should jumped to or scrolled to the 5th menu but now its stays or displays in menu 1 or whatever last menu was clicked only.
My expectation is to create like this eg.
https://js.devexpress.com/Demos/WidgetsGallery/Demo/Pivot/Overview/jQuery/iOS/
I am looking to Achieve two scenario, but I am failing and getting every time an error
If I Make the menu(selected menu) left or center side align then it should always be in left or center side align in initial load of the screen and also when I am swipe the slide content the menu should left or center align, sample eg. above link devexpress
When a content is swiped eg. 5th panel slide then the menu should scroll with respect to it
What I have tried is here and also the Jquery code html for reference

Scrolling sidebar inside a div with scrollbar - $(window).on('scroll', function()?

I want my social sidebar make scroll only within the gray div. I have already put the sidebar within the gray div does not exceed the footer or the content above. My difficulty is to sidebar scroll accompanying the scroll without going gray div.
http://test.eae.pt/beautyacademy/angebot/
JS:
beautyAcademy.sharer = {
element: void 0,
elementToScroll: void 0,
init:function() {
this.element = $('.js-sharer-ref');
console.log(this.element.length);
if(this.element.length != 1) {
return;
}
this.build();
},
build: function() {
this.binds();
},
binds: function() {
var _this = this;
// Element that's gonna scroll
this.$elementToScroll = $('.fixed-social');
// Element that's gonna scroll height
this.elementToScrollHeight = this.$elementToScroll.outerHeight();
// Element where scroll is gonna happen Height
this.elementHeight = this.element.outerHeight();
// Element where scroll is gonna happen distance to top
this.elementOffsetTop = this.element.offset().top;
// Scroll that was done on the page
this.windowScrollTop = $(window).scrollTop();
this.elementOffsetBottom = this.elementOffsetTop + this.elementHeight - this.elementToScrollHeight;
this.$elementToScroll.css('top', (_this.elementOffsetTop+80) + "px");
$(window).on('scroll', function() {
if(this.windowScrollTop + this.elementToScrollHeight < this.elementHeight )
this.$elementToScroll.css('margin-top', this.windowScrollTop );
});
}
};

You need to try like below :
$(function(){
if ($('#container').length) {
var el = $('#container');
var stickyTop = $('#container').offset().top; // returns number
var stickyHeight = $('#container').height();
$(window).scroll(function(){ // scroll event
var limit = $('#footer').offset().top - stickyHeight - 20;
var windowTop = $(window).scrollTop(); // returns number
if (stickyTop < windowTop){
el.css({ position: 'fixed', top: 0 });
}
else {
el.css('position','static');
}
if (limit < windowTop) {
var diff = limit - windowTop;
el.css({top: diff});
}
});
}
});

Add class to element if at top of page and user scrolls up

I'm trying to create a splash page similar to http://kinkinurbanthai.com/ but I need to re-activate the splash if the user is at the top of the page, and does an additional scroll up to 'request' or activate the splash again.
I have the code working up to the point of reactivating the splash element; but I can't get it to wait for the additional 'scroll up' request.
Here is the code so far that works, minus the locking b/c that isn't doing what I need it to atm. Code: http://jsfiddle.net/teejudp3/2/
// Does stuff on load and scrolls
//-------------------------------//
$(window).on("load scroll",function(e){
var $window = $(window);
if ( $window.scrollTop() <= 0 ) {
$('.splashwrapper').removeClass('remove');
}
// hide/show splash screen
//=========================//
// chrome/FF
$('.splashwrapper').bind('DOMMouseScroll', function(e){
// get scroll direction
var direction = (function () {
var delta = (e.type === 'DOMMouseScroll' ?
e.originalEvent.detail * -40 :
e.originalEvent.wheelDelta);
return delta > 0 ? 0 : 1;
}());
if( direction === 0 ) {
// scroll up
} else {
// scroll down
$('.splashwrapper').addClass('remove');
}
//prevent page fom scrolling
return false;
});
//IE, Opera, Safari
$('.splashwrapper').bind('mousewheel', function(e){
// get scroll direction
var direction = (function () {
var delta = (e.type === 'DOMMouseScroll' ?
e.originalEvent.detail * -40 :
e.originalEvent.wheelDelta);
return delta > 0 ? 0 : 1;
}());
if( direction === 0 ) {
// scroll up
} else {
// scroll down
$('.splashwrapper').addClass('remove');
}
//prevent page fom scrolling
return false;
});
// touch device - uses touchSwipe.js
$(".splashwrapper").swipe({
swipeUp:function() {
$('.splashwrapper').addClass('remove');
}
});
});
I've tried to stop the users scroll if they go to <= 1 scroll top position but this doesn't seem to give the wanted affect.
// temporarily lock users scroll position
var $window = $(window), previousScrollTop = 1, scrollLock = false;
$window.scroll(function(event) {
if(scrollLock) {
$window.scrollTop(previousScrollTop);
}
previousScrollTop = $window.scrollTop();
});
// if at 1px from top, stop scroll from going up one time
if ( $window.scrollTop() <= 1 ) {
scrollLock = true;
$window.scrollTop( 1, 0);
setTimeout(function() {
scrollLock = false;
}, 1000);
}

Got this working by re-working the stop-point section - aka I was overthinking it.
Updated fiddle: http://jsfiddle.net/teejudp3/6/
var $window = $(window);
if ( $window.scrollTop() === 0 && $('.splashwrapper').hasClass('ready') ) {
$window.scrollTop(1);
$('.splashwrapper').removeClass('ready').removeClass('remove');
}
if ( $window.scrollTop() === 0 && !$('.splashwrapper').hasClass('ready') ) {
$window.scrollTop(1);
setTimeout(function() {
$('.splashwrapper').addClass('ready');
}, 500);
}

trigger a jquery effect when you scroll

Hey guys I'm back with another question. I'm using the code below to add a bouncing effect to a div on my site. It works fine right now but the div has to be clicked in order for the effect to start. I would like to modify it so that when the user is scrolling down the page and reaches that section it triggers the effect automatically. How can I modify the code below to trigger the effect when the user scroll's down and reaches that section of the site?
Here is the code I' using
$(".servi-block").click(function () {
doBounce($(this), 2, '10px', 150);
});
function doBounce(element, times, distance, speed) {
for (i = 0; i < times; i++) {
element.animate({
marginTop: '-=' + distance
}, speed)
.animate({
marginTop: '+=' + distance
}, speed);
}
}

$(window).scroll(function(event){
isElementVisible = inViewport($(".servi-block"));
if(isElementVisible)
{
doBounce($(this), 2, '10px', 150);
}
});
function inViewport (el)
{
var r, html;
if ( !el || 1 !== el.nodeType ) { return false; }
html = document.documentElement;
r = el.getBoundingClientRect();
return ( !!r
&& r.bottom >= 0
&& r.right >= 0
&& r.top <= html.clientHeight
&& r.left <= html.clientWidth
);
}

This should help you out: http://api.jquery.com/scroll/
$( "#target" ).scroll(function() {
$( "#log" ).append( "<div>Handler for .scroll() called.</div>" );
});
Also utilize this
$('#target').on("mousewheel", function() {
alert($(document).scrollTop());
});
Those two together should get you the ability to figure out you are scrolling, and when you reach position X, do something.
EDITED
Let's go at it this way -
var targetPos = "500px";
$( document ).scroll(function() {
if ($(document).scrollTop() == targetPos) {
doBounce($(this), 2, '10px', 150);
}
});

You can simply check to see when the element comes into view by taking the element's offset and subtracting that element's parent height and scrollTop value.
Here's an example:
$(document).ready(function() {
$(document).on('scroll', function() {
var offset = $('.element').offset().top,
scroll = $(document).scrollTop(),
height = $(document).height(),
inViewDown = ((offset - scroll - height) <= 0) ? true : false;
if (inViewDown) {
// Do some stuff
}
});
});
Here's a working example: http://jsfiddle.net/ughEe/

Getting a floating div to stop upon reaching another div

I have a floating div on the sidebar that scrolls with the page. Is there a way to add code that makes it stop when it reaches the footer?
See code in action: http://openbayou.staging.wpengine.com
jQuery code used to float div:
$j=jQuery.noConflict();
$j(document).ready(function($) {
//this is the floating content
var $floatingbox = $('#one');
if($('#primary').length > 0){
var bodyY = parseInt($('#primary').offset().top) - 20;
var originalX = $floatingbox.css('margin-left');
$(window).scroll(function () {
var scrollY = $(window).scrollTop();
var isfixed = $floatingbox.css('position') == 'fixed';
if($floatingbox.length > 0){
$floatingbox.html();
if ( scrollY > 1561 && !isfixed ) {
$floatingbox.stop().css({
position: 'fixed',
top: 10,
});
} else if ( scrollY < 1561 && isfixed ) {
$floatingbox.css({
position: 'relative',
top: 0,
});
}
}
});
}
});

Why not just set the z-index of the sidebar behind the z-index of the footer?
EDIT: I didn't like the result of this so I went and made this work in jquery the way you want it...
try this for your scroll function:
$(window).scroll(function () {
floatingbox = $("#one");
if(floatingbox.length > 0){
//get our current scroll position
var scrollY = $(window).scrollTop();
//get the position of the tag cloud relative to the document
var contentY = ($("#sidebar .sidebar-tag-cloud").offset().top + $("#sidebar .sidebar-tag-cloud").outerHeight(false));
//calculate the largest possible top margin size before it starts to overlap the footer
var lastY = $("#footer").offset().top - $("#one").outerHeight(false);
//check if our scroll location is past the bottom of the tag cloud
if ( scrollY > contentY )
{
//check if the current top position is less than the maximum position
if(floatingbox.offset().top<lastY)
{
//keep scrolling
floatingbox.stop().animate({"marginTop":scrollY-contentY});
}else
{
//check if we have scrolled back up and have a space at the top
if(scrollY<floatingbox.offset().top)
{
floatingbox.stop().animate({"marginTop":scrollY-contentY});
}else
{
// hard set to the maximum position
floatingbox.stop().css({"marginTop":lastY-contentY});
}
}
}
}
});
I also made it a little more dynamic by getting the location of the bottom of the tag cloud and using that instead of your hard-coded number.

Alright, after looking at your latest jsfiddle. I have modified that code to work with yours. http://jsfiddle.net/Tgm6Y/4430/ This will not have the animate lag and should work well for you.
$('#one').followTo('#two','#pointFive');
just replace #two with #footer and #pointFive with "#sidebar .sidebar-tag-cloud" and this should work in your code.

UPDATE: Found a solution to my problem.
$(function () {
var msie6 = $.browser == 'msie' && $.browser.version < 7;
if (!msie6) {
var top = $('#one').offset().top;
$(window).scroll(function (event) {
var y = $(this).scrollTop() + 20;
if (y >= top) {
$('#one').addClass('fixed');
}
else {
$('#one').removeClass('fixed');
}
// don't overlap the footer - pull sidebar up using a negative margin
footertotop = ($('#footer').position().top);
scrolltop = $(document).scrollTop() + 760;
difference = scrolltop - footertotop;
if (scrolltop > footertotop) {
$('#one').css('margin-top', 0 - difference);
}
else {
$('#one').css('margin-top', 0);
}
});
}
});
What this does is it stops before the footer and I can configure the stopping point.
I appreciate all the help in solving my problem!
